Terrible, pointless trash. It's interesting that this and Wolf Creek were released within a few weeks of each other, because they could serve as a film school lesson in the good and bad of this subgenre- like Saw vs. Oldboy or Audition.
It's difficult to know where to begin with Hostel, there are just so many things wrong with it. Meaningless, boring subplots, sloppy editing, and it even feels too long for a 90 min. film. This is the kind of script that makes you wonder how it ever got into production. And in a genre that usually overextends itself in terms of style there's a puzzling absence of any artful aesthetic touches. Overall, just a mess.
